Abstract

Methods and apparatus related to partitioning traffic segments are described. An access router, having concurrent connections with two access terminals and desiring to transmit traffic signals to the two access terminals in the same traffic segment, partitions a traffic segment. The partition is such that a first portion of the traffic segment is allocated to a first access terminal and a second portion of the traffic segment is allocated to the second access terminal. Control information, e.g., identifying partition portion assignments, data rate and/or coding information, is also communicated in the traffic segment as in-band control signaling. An access terminal, to which some of traffic signals are directed, receives and recovers the in-band control signaling, identifying its allocated partition portion of the traffic segment and identifying data rate and/or coding information used. The access terminal receives the traffic segment signals in its allocated partition portion and recovers the traffic information.

Claims

1. A method of operating a first access terminal, the method comprising:

receiving first traffic segment signals in a first traffic segment from an access router;

recovering from the first traffic segment signals partitioning information;

at least based on the recovered partitioning information, determining a portion of the first traffic segment signals which includes traffic data corresponding to the first access terminal;

recovering data rate information from the first traffic segment signals, the data rate information indicating a data rate used for the portion of the first traffic segment signals;

transmitting a first transmission request response corresponding to the first traffic segment to said access router;

transmitting a second transmission request response to the access router, the second transmission request response corresponding to a second traffic segment;

receiving second traffic segment signals, said second traffic segment being a non-partitioned segment; and

recovering traffic data corresponding to the first access terminal communicated in the second traffic segment, said second traffic segment being used to communicate information to the first access terminal.

2. The method of claim 1, wherein the first and second traffic segments are of the same size.

3. A first access terminal comprising:

at least one processor configured to;

receive first traffic segment signals in a first traffic segment from an access router;

recover from the first traffic segment signals partitioning information;

at least based on the recovered partitioning information, determine a portion of the first traffic segment signals which includes traffic data corresponding to the first access terminal;

recover data rate information from the first traffic segment signals, the data rate information indicating a data rate used for the portion of the first traffic segment signals;

transmit a first transmission request response corresponding to the first traffic segment to said access router;

transmit a second transmission request response to the access router, the second transmission request response corresponding to a second traffic segment;

receive second traffic segment signals, said second traffic segment being a non-partitioned segment; and

recover traffic data corresponding to the first access terminal communicated in the second traffic segment, said second traffic segment being used to communicate information to the first access terminal; and

memory coupled to said at least one processor.

4. A first access terminal comprising:

means for receiving first traffic segment signals in a first traffic segment from an access router;

means for recovering from the first traffic segment signals partitioning information;

means for determining a portion of the first traffic segment signals which includes traffic data corresponding to the first access terminal, at least based on the recovered partitioning information;

means for recovering data rate information from the first traffic segment signals, the data rate information indicating a data rate used for the portion of the first traffic segment signals;

means for transmitting a first transmission request response corresponding to the first traffic segment to said access router;

means for transmitting a second transmission request response to the access router, the second transmission request response corresponding to a second traffic segment;

means for receiving second traffic segment signals, said second traffic segment being a non-partitioned segment; and

means for recovering traffic data corresponding to the first access terminal communicated in the second traffic segment, said second traffic segment being used to communicate information to the first access terminal.

5. A computer program product comprising:

a computer readable medium comprising;

code for causing at least one computer to receive first traffic segment signals in a first traffic segment from an access router;

code for causing the at least one computer to recover from the first traffic segment signals partitioning information;

code for causing the at least one computer to, at least based on the recovered partitioning information, determine a portion of the first traffic segment signals which includes traffic data corresponding to the first access terminal;

code for causing the at least one computer to recover data rate information from the first traffic segment signals, the data rate information indicating a data rate used for the portion of the first traffic segment signals;

code for causing the at least one computer to transmit a first transmission request response corresponding to the first traffic segment to said access router;

code for causing the at least one computer to transmit a second transmission request response to the access router, the second transmission request response corresponding to a second traffic segment;

code for causing the at least one computer to receive second traffic segment signals, said second traffic segment being a non-partitioned segment; and

code for causing the at least one computer to recover traffic data corresponding to the first access terminal communicated in the second traffic segment, said second traffic segment being used to communicate information to the first access terminal.
